WebThe Texas Orocline, with a half wavelength of similar to 120 km, is the largest and most obvious orocline in the southern New England Orogen and is clearly recognised in … WebThe main outcome is recognition that the Texas Orocline was nucleated during subduction of a seamount chain resulting in orogenic curvature of the Carboniferous subduction complex. Subduction of the seamount chain is shown by abundant limestone associated with ocean island basalts amongst the accreted turbidites in the core of the Texas Orocline.
WebThe northern oroclinal pair comprises the Texas orocline in the northwest and the Coffs Harbour orocline in the southeast (Flood and Fergusson 1982; Korsch and Harrington 1987) (Figs. 1b, c). The pair has a clockwise sense of rotation. WebAlternatively, I propose that the Texas Orocline formed through multiple stages, with an initial curved structure that may have resulted from subduction rollback or a pre-existing curvature in the palaeomargin of eastern Australia. This initial curvature was amplified by subsequent contractional deformation. Structural observations were also ...

[7] The Maipo Orocline or Maipo Transition Zone is an orocline located between 30° S and 38°S in the Andes with a break in trend at 33° S. [8] The Arauco Orocline a subtle orocline located at 37° S in south-central Chile. It marks a seaward-convex bend in the Andes.
WebSep 15, 2011 · The orocline has an along strike extent of some 600 km and a width of around 350 km. It is defined by the folding of a convergent plate margin assemblage, and developed during the late Paleozoic to early Mesozoic Gondwanide orogeny [ Korsch and Harrington, 1987; Cawood et al., 2011 ].

The term was introduced by S. Warren Carey in 1955 in a paper setting forth how complex shapes of various orogenic belts could be explained by actual bending, and that understanding this provided "the key to understanding the evolution of the continents". Carey showed that in a dozen cases where such bends were un… original gentleman
